⁽¹⁾ Mineral Resources are presented inclusive of Mineral Reserves. Numbers may not sum due to rounding.

⁽²⁾ The Mineral Reserves for El Castillo and San Agustin, which together form the El Castillo Complex, set out in the above table were taken from the El Castillo Complex Technical Report, including depletion through mining activities and changes to recovery and cost assumptions from July 1, 2017 to December 31, 2018, are valid as of December 31, 2018 and used a gold price of $1,200 per ounce and silver price of $14 per ounce. Cut-off grades, depending on rock and ore type, varied from 0.14 g/t AuEq for oxide to 0.57 g/t Au for silicified sulphide.

⁽³⁾ The Mineral Reserves for La Colorada set out in the above table were taken from the La Colorada Technical Report, including depletion from July 1, 2017 to December 31, 2018 through mining activities, are valid as of December 1, 2018 and used a gold price of $1,200 per ounce and silver price of $14 per ounce. Cut-off grades, depending on deposit, varied from 0.12 g/t AuEq to 0.14 g/t AuEq.

⁽⁴⁾ The Mineral Reserves for Magino set out in the table above were taken from the Magino Technical Report. The Mineral Reserve was estimated at a gold price of $1,200 per ounce. The Mineral Reserve used a gold cutoff of 0.41 g/t.
